Turning loops of the Toronto streetcar system serve as termini and turnback points for streetcar routes in Toronto, Ontario, Canada. The single-ended streetcars require track loops in order to reverse direction. Besides short off-street track loops these can also be larger interchange points, having shelters and driver facilities, or be part of a subway station structure for convenient passenger interchange.
